Please help about Jupyter file support

Description

I 100% followed the instruction of external renderers on the docs, and even fork the repository to build a new docker image. No matter what it return an error:

Render, jupyter render run command jupyter-nbconvert [--stdin --stdout --to html --template basic] failed: exec: "jupyter-nbconvert": executable file not found in $PATH

Part of logs:

`2024/07/18 02:39:06 ...es/charset/escape.go:41:EscapeControlReader() [E] Error whilst escaping: jupyter render run command jupyter-nbconvert [--stdin --stdout --to html --template basic] failed: exec: "jupyter-nbconvert": executable file not found in $PATH

I just transferred my code to gitea a few days ago, maybe I am not familiar enough with gitea. But please offer some solutions of how to solve this issue.

Gitea Version

1.22.1

Can you reproduce the bug on the Gitea demo site?

No

Log Gist

No response

Screenshots

No response

Git Version

Operating System

Docker on Linux

How are you running Gitea?

I first used the offical docker image, and tried to install external renderers using command line. After that, I tried to build a docker image with these renderers, but it still returned the same error as mentined above.

Database

MySQL/MariaDB

It is jupyter nbconvert in the document.
But in your error logs, it seems that you are using jupyter-nbconvert

Sorry, I didn't mention that. I tried both "jupyter-nbconvert" and "jupyter nbconvert". Scroll down, and you can see another instruction about jupyter notebook, that one uses "jupyter-nbconvert".

I think the problem is this. Even you have installed them, but they are not in PATH, so Gitea can not use it.
As a simple solution, you can install them into /usr/local/bin,

RUN PIPX_HOME=/opt/pipx PIPX_BIN_DIR=/usr/local/bin pipx install jupyter docutils --include-deps

See: pypa/pipx#754

And also if the rendering was failed, we should not show 500 error page, a flash error is enough I think.

It works! Thank you very much. I think you can add this to the docs. Wonderful project by the way.

Update: There's a more simple solution.
